My dealer has a touchless system that they run it through. I've seen what they do, but it doesn't get the car clean really at all. It just gets a little dirt off of the outside and you're left with a wet car that, once you drive away, slings dirt back onto the sides anyway. Pretty pointless.
I've always told them not to do it to mine anyway. You're better off doing it yourself.
